I agree with Ali that one has to broaden the definition a bit. It stands to reason that the adventure genre have evolved, as have most other genres. Frequently the genres borrow from each other. There were action sequences in Sierra and Lucasarts adventures, too.
I believe that some changes in distribution and gameplay were better suited to other genres than adventure games, and it took some time to catch up. Shareware seemed more popular with games with defined levels, where you could play the first levels for free, then pay for the whole game. Casual mobile games, like hidden object games, have embraced this by now. Also online multiplayer doesn't translate easily for adventure games, at least not without incorporating combat, quests or roleplaying.
On the other hand, I would argue that it is common today that even games not remotely adventures have borrowed the cut scene story telling technique, be it a shooter or a Mario game, you are treated to movie clips telling the story between levels. So the influence works both ways.
In recent years, the Escape Room games have become very popular. Those are definitely adventure games, but often with huge amounts of moon logic and little or no story.
